Title: Numerical controller for external form working machine
Inventor: ARAFUJI SHIGENORI
IPC: B23Q15/00
Filed: 1988-11-01
Abstract: PURPOSE:To set a writing program to be written into an input medium with use of the data on the X and Y axes only and to attain the control of a three- dimensional axis by preparing a sizing drive control part where the data on a Z axis is preset. CONSTITUTION:An input part 1a reads a data medium where the diameter of a working tool and the start point, the relay point (flexion point) and the end point of a working form are successively written. Based on the data read by the part 1a, an X/Y axis drive control part 2a produces the control commands for an X axis drive part 3a and a Y axis drive part 3b with the X and Y data commands and revolve the X and Y axes to drive an X/Y table. Thus the working is started for the external form of a printed circuit board. Then the coordinate data on the Z axis written into a memory part of a sizing drive control part 5 is read with the working end signal of the part 1a. The part 5 gives a command to a Z axis drive part 3c and moves a cutter head up. Thus a cutter is pulled out of the circuit board. As a result, the three- dimensional axis control is attained without incorporating the data on the Z axis into a program which is prepared based on the coordinate data on both X and Y axes.

Title: Adaptive filter device
Inventor: SAKAZAKI YOSHIHISA
IPC: H03H21/00
Filed: 1994-11-11
Abstract: PURPOSE: To provide excellent expanded pictures by appropriately setting the characteristics of a filter means arranged in the post stage of an expansion means matching the characteristics of distortion and a frequency band provided in data to be transmitted. CONSTITUTION: A special reproduction data generation circuit 2 generates the data for special reproduction from packet-transmitted compressed data and a filter factor corresponding to the data for the special reproduction is decided by a filter factor decision circuit 3. A data mixing circuit 4 mixes and outputs the compressed data, information for indicating the data for the special reproduction and the information for indicating the filter factor. Thereafter, a decoder 8 selects one data, expands them and supplies them to a filter 9. Simultaneously, a reproduction circuit 7 detects a reproducing data filter factor and supplies it to the filter 9. The filter 9 switches the frequency band, limits the frequency band of input signals and performs output based on the supplied filter factor.  Thus, the need of setting the filter factor by a user is eliminated on an expansion side and appropriate filter characteristics are realized at all times.
